Question

Find the coloring cost pf the sphere if the radius of the sphere is 6cm

Answer 1

Answer:

Step-by-step explanation:

area of sphere = 4πr^2

radius of sphere= 6 cm

= 4*22/7 * 6^2

4*22/7*36

3168/7

= 452.57 cm^2

Answer 2

Radius of the sphere = 6cm

TSA of sphere = 4πr²

= 4 * 22/7 * 6 * 6

= 4 * 3.14 * 36

=452.16 cm²

So TSA of the sphere = 452.16 cm²

To find the coloring cost of the sphere multiply the TSA of the sphere with the cost of coloring per cm²
